This is a nonconformity. the contact is between an igneous and sedimentary rock formation. Granite should be on the bottom and sandstone on top, If this is not the case then some type of over-turning has taken place. The depositional envornment allowed sand to acculate over the top of the granite and later consolodated into a rock. This is called a contact. Many years ( perhaps millions) passed) before the whole mass became a rock formation. Can you identify other contacts in the area? If so, you may be able to date this contact and correlate it to other areas in your vicinity. See if you can trace it and look on geologic maps to see if it is mapped. If not, you may have found something that no one has yet discovered.
Granite is composed of interlocking grains, a result of minerals solidifying at different temperatures as they cool from magma. This interlocking structure makes granite very durable and hard. Sandstone is formed of cemented sand sized grains. The bond between grains is not as strong as the interlocking grain found in granite.
The pyramids in Egypt are primarily made of limestone blocks, with some parts constructed using granite and sandstone. The limestone was quarried locally and the granite was transported from Aswan, about 500 miles away. Sandstone was also used for some of the outer casing stones.
Yes, people can sell stone in the form of raw materials such as granite, marble, or sandstone, as well as finished goods like sculptures, countertops, and tiles. Stone is commonly bought and sold in the construction and landscaping industries for various projects.
Granite in Canada is mined in various locations, including Quebec, Ontario, British Columbia, and Nova Scotia. Each province has specific regions known for granite mining due to the high quality and quantity of granite deposits.
Some of the granite mines in Zhytomyr, Ukraine include Korostyshev Quarry and Khoroshevsky Quarry. These mines produce high-quality granite used in construction, monuments, and other applications. The granite mining industry in Zhytomyr plays a significant role in the local economy.
If a sandstone in contact with a granite contains fragments of the granite, it suggests that the granite is older than the sandstone. The presence of granite fragments indicates that the granite was likely eroded and its material was transported and deposited to form the sandstone. This relationship can also imply that geological processes, such as weathering and erosion, played a significant role in shaping the landscape between the two rock types.
The sandstone is older because it must have been there first to provide the small pieces found in the granite. This relationship implies that the sandstone layer was already in place before the granite formed and incorporated fragments of the sandstone.
The granite would be older because it had to form first in order for the sandstone to contain pieces of it. The sandstone would have formed later on top of the granite layer.
granite is older, Granite goes back more than 300 mya to the Ancestral Rockies or the first Rocky Mountains-Fountain Formation
Granite becomes Sandstone when water erodes the Granite on Earths surface, and then deposits the sediment.
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.

Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.

Sedimentary rock and igneous rock would most likely have a zone of contact metamorphism between them. When molten magma intrudes into the surrounding rock, the heat and fluids released can alter the mineral composition of the adjacent rocks, leading to contact metamorphism.
Granite is typically harder than sandstone. Granite is an igneous rock that forms from the cooling of molten magma, making it more dense and resistant to abrasion compared to sandstone, which is a sedimentary rock.
